I am running into a strange error with Swift 3.
I am trying to request a URL in a Swift application but the request always fails. I have tried opening different URLs and opening the URLs in my browser, where the requests work.
I am using the following code snippet I found online:
let url = URL(string: "https://httpbin.org/ip")
let task = URLSession.shared.dataTask(with: url!) { data, response, error in
guard error == nil else {
print(error!)
return
}
guard let data = data else {
print("Data is empty")
return
}
let json = try! JSONSerialization.jsonObject(with: data, options: [])
print(json)
}
task.resume()
This is the error my program is producing

I am suspecting this issue could be caused by me being on eduroam, the heavily gated university wifi. On the other hand other requests (from other macOS) applications are working fine.
Additionally there should be no issues with misconfiguration on the Mac is it is brand new and only homebrew and a few programs have been installed.
I am looking forward to any pointers you might have and would like to thank you in advance.

I am trying to implement an Google AdMob banner ad in my swift application and it simply doesn't show up. I extended the plist to the following.
<key>GADApplicationIdentifier</key>
<string>ca-app-pub-???</string>
<key>SKAdNetworkItems</key>
<array>
<dict>
<key>SKAdNetworkIdentifier</key>
<string>cstr6suwn9.skadnetwork</string>
</dict>
...
</array>
Edited AppDelegate.swift...
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
GADMobileAds.sharedInstance().start(completionHandler: nil)
return true
}
And implemented the banner in my ViewController...
import UIKit
import GoogleMobileAds
class ViewController: UIViewController {
...
private let banner: GADBannerView = {
let banner = GADBannerView()
banner.adUnitID = "ca-app-pub-???/???"
banner.load(GADRequest())
banner.backgroundColor = .secondarySystemBackground
return banner
}()
override func viewDidLoad() {
super.viewDidLoad()
banner.rootViewController = self
view.addSubview(banner)
...
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
banner.frame = CGRect(x: 0, y: view.frame.size.height-50, width: view.frame.size.width, height: 50)
}
...
}
This code causes the following error and the banner doesn't show up:

Initialisation of GADBannerView is might be wrong in your project as they need adSize as frame
this working fine on my application , I have working production ads,
class HomePageViewController: UIViewController {
private var adMobBannerView1: GADBannerView!
private var adMobBannerView2: GADBannerView!
override func viewDidLoad() {
setupAdMobBannerAD()
}
private func setupAdMobBannerAD() {
let sizeForBanner = GADAdSizeFromCGSize(.init(width: view.frame.width, height: 50))
// here you need to intilise GADBannerView with adSize of GADAdSizeFromCGSize
adMobBannerView1 = GADBannerView(adSize: sizeForBanner)
adMobBannerView2 = GADBannerView(adSize: sizeForBanner)
adMobBannerView1.translatesAutoresizingMaskIntoConstraints = false
adMobBannerView2.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(adMobBannerView1)
view.addSubview(adMobBannerView2)
adMobBannerView1.delegate = self
adMobBannerView2.delegate = self
NSLayoutConstraint.activate([
adMobBannerView1.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor),
adMobBannerView1.centerXAnchor.constraint(equalTo: view.safeAreaLayoutGuide.centerXAnchor),
adMobBannerView2.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor , constant: 20 ),
adMobBannerView2.centerXAnchor.constraint(equalTo: view.safeAreaLayoutGuide.centerXAnchor),
])
adMobBannerView2.adUnitID = Constants.secondAdBannerString
// I have saved my bannerID String in another class don't worry about this
adMobBannerView2.rootViewController = self
adMobBannerView1.adUnitID = Constants.firstAdBannerString
// I have saved my bannerID String in another class don't worry about this
adMobBannerView1.rootViewController = self
adMobBannerView2.load(GADRequest())
adMobBannerView1.load(GADRequest())
}
}
you want to add some delegate to get informed by admob if there is any problem with your ad account or something
extension HomePageViewController : GADBannerViewDelegate {
func bannerView(_ bannerView: GADBannerView, didFailToReceiveAdWithError error: Error) {
print("admob banner ad failecd to show going to represent adolony \n")
if DataModel.shared.showAdmobAd {
self.requestAdColonyBanners()
// any alternative method can be performed here as we this function will be called by admob incase you didn't get banner ad , in my case I m launching ads form another ad service called adcolony
}
}
}
I tried to search for this error a lot did not found any solution for it.
Details:
Made a request to API through retrofit, getting success response for the real devices but getting failure response if request is been made from android emulator.
public void loadPostsToDB() {
Call<List<Post>> call = mAPIServiceInterface.getAllPosts();
call.enqueue(new Callback<List<Post>>() {
#Override
public void onResponse(Call<List<Post>> call, Response<List<Post>> response) {
List<Post> posts = response.body();
new InsertPostAsyncTask(mDaoInterface,posts).execute();
}
#Override
public void onFailure(Call<List<Post>> call, Throwable t) {
Log.e("Failure Reason : "," "+t.toString());
}
});
}
In above code gives response, I checked through debugging, as per it, point hits on success when ran from real device but failure function debug point got hit if ran from emulator.
Below is the log which got printed.

Any suggestion? what might be causing this behaviour?
The issue got solved,
It was required change from server side for certificates.

when i call rdd.foreach(send_http), rdd=sc.parallelize(["http://192.168.1.1:5000/index.html"]),
send_http defined as follow:
def send_http(url):
req = urllib.request.Request(url)
resp = urllib.request.urlopen(req)
anyone can tell me the problem? thanks.
This is #tmylt's answer in the comment above, but I too can confirm that using http.client instead of requests.get does work. I'm sure there's a reason why this is happening, but using python http.client is a quick fix.
I want so send a message to the localhost on port number 80 but I was able to open a connection What did i do wrong and how can I fix it?
Here is the code to connect to the localhost server
class client:NSObject {
var inputstream = InputStream!
var outputstream = OutputStream!
func setupNetworkCom() {
var readstream = Unmanaged<CFReadStream>?
var writestream = Unmanaged<CFWriteStream>?
CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, "localhost" as CFString, 80, &readstream, &writestream)
inputstream = readstream!.takeRetainedValue()
outputstream = writestream!.takeReatainedValue()
inputstream.schedule(in: .current, forMode: .common)
outputstream.schedule(in: .current, forMode: .common)
inputstream.open()
outputstream.open()
}
}
It gives me this error

This question and your Other question have the same answer you're missing the entitlement in the capabilities tab.
click on your project settings and go to capabilities there you'll see the app sandbox. make sure it's turned on and then enable incoming connections and outgoing connections.
